UPDATED -- Truckload carrier Swift Transportation Co. saw its net income decline in the first quarter of the year while profit for the time definite surface transportation and logistics provider Forward Air Corp. more than doubled as refrigerated hauler Marten Transport Ltd. reported a boost in two ways.

One of the nation’s largest trucking companies reported improved earnings for the final quarter of last year and beating its expectations for all of 2015 while another publicly held fleet's latest three-month numbers failed to live up to its annual performance.

Swift Transportation has lowered projections for profits for the final two quarters of the year and for the full year, due in large part to at least one accident, legal claims and expected lower freight volume.

Swift Transportation Co. tripled its net income in the first quarter of the year, totaling $37.8 million, or diluted earnings per share of 26 cents, compared to $12.3 million, or 9 cents per share a year earlier.

With year-over-year profitability improvements in its truckload, intermodal and refrigerated segments, Swift Transportation saw its net income surge to $50.2 million in the third quarter, compared to $30 million a year ago.

Trucking company Swift Transportation has announced it expects adjusted earnings per share to range between 33 and 36 cents per share for the fourth quarter of 2013, compared to its previous expectation of 40 cents per share.

The Truckload Carriers Association has announced the name of its latest Highway Angel: David Kus of Fredericksburg, Penn., who drives for Swift Transportation. Kus is being recognized for acting quickly when a fellow motorist had an accident and then inadvertently put himself in more danger.
